question 2:I think you can probably just get a different bunch of artwork. There are a few people on the site who make different artwork for the cards and backgrounds and stuff, and they host it various places. Maybe in the development section?

question 3::Yes I think this is obsolete now, you can ignore it

question 4:There is multiplayer in the client but I think it got broken some time. It used to work I think in Manalink 2, and then broke some time around Manalink 3. I am hoping they will fix it some day. You can play the official MTG Online, but you would have to pay for the cards to do that. It's good, but it can get expensive.

question 5:I heard Pokemon is good, but I have never tried it. I thought it was a childrens game because the artwork looks like it is for young people, but then a friend of mine told me it's a fun game to play and he plays it sometimes instead of MTG. I will try it some time... I'm so lazy
